Afaik , the standard bsw mids dont have a xover as they are intended for factory amp power. They dd bring a new kit to market intended for aftermarket power which includes a dedcated xover.

Yep...I ordered one of those new component kits when I was trying to solve the distortion problem that turned out to be caused by my defective ipod.

I am going to return them but was thinking of exchanging for the drop-ins. The factory speakers sound pretty good powered by the JL XD600....I'm not sure if it is worth taking off the door panels to make the change...
